Embodiment
Method of the present invention is moved in data modeling relevant with geometry entity and/or process computer system 1.
This computer system 1 can be used by the user of data modeling relevant with geometry entity that does not demonstrate and/or handling procedure 11, can use or not use method of the present invention on this computer system 1.This computer system 1 can also show the figure signal that derives from by graphical interfaces 13 cards of graph function routine library 12 controls on graphic alphanumeric display 14.
In the back of this narration, in order to simplify more, the data modeling relevant and/or handle 11 program 11 and also can be expressed as graphical application 11 with geometry entity.
In preferred Implementation Modes of the present invention, the computer system 1 that is used for moving the inventive method is a computing machine, this computing machine can use the Windows operating system of Microsoft company, in this operating system, the display routine of geometric data is to meet the figure API (for the advanced programming interface) that carries out such as the dynamic link library (DLL) of the OpenGL standard of SiliconGraphics company by editor.This DLL is usually located in the Windows system directory, is named as opengl32.dll.
The OpenGL routine library comprises many functions, in this narration, and the whole OpenGL function of Shi Yonging as an example, no matter be to use method of the present invention, still do not use the inventive method, all have a mind to be confined to the subclass of simplifying very much of OpenGL, in this narration, can keep rational total amount.Yet, should understand well thus, principle of the present invention not only is limited to the OpenGL function that exists in this narration, and is applied to the various functions that exist in the OpenGL standard equally.
Referring to Fig. 1, data output method of the present invention is not used in narration now, shows the operation logic of geometric model 10 on graphic alphanumeric display 14.
When the graphical application 11 of hope showed a geometric model on graphic alphanumeric display 14, it called graphical interfaces 12 graph function that is arranged in DLL.This graphical interfaces 12 is sent to graphics card 13 with the instruction of vectorial type through its relevant Control Software.
Described display by cathode-ray tube (CRT) or similarly device form, the scanning by video-type shows, therefore, must store the scale-of-two image of the graph data that is shown, so that user 2 can keep the reservation visually of display graphics data.But for each display dot of display 14, this scale-of-two image of being made up of a certain amount of binary digit just is stored in the internal storage of the graphics card 13 that is called as the image refreshing storer.Information generation by per second is read this scale-of-two image for more than 20 time again and read again by the representative vision signal of the image in the image refreshing storer that is stored in graphics card 13 has just been obtained keeping for user 2 data vision by graphics card.Graphics card 13 is just delivered to these vision signals on the graphic alphanumeric display 14, and here they are shown the image that is stored in the image refreshing storer of graphics card 13 with binary mode.
Therefore, the graphical application 11 of wishing to show geometric model 10 on graphoscope 14 will be carried out calling of graph function among a series of DLL of being present in OpenGL.In the OpenGL standard, calling of these a series of graph functions ends at calling of specific function, and this will finish the process of the instruction transformation of delivering to card 13 for the binary point of demonstration on graphic alphanumeric display 14.
Such as, in order to show that their coordinate is respectively by two leg-of-mutton (strip) T1 of the some ABC by coordinate and BCD and the geometric models 10 that T2 forms respectively:
A：(0，10，0)；
B：(0，10，-10)；
C：(0，0，0)；
D：(0，0，-10)；
Carry out calling of graph function according to DLL OpenGL graphical application 11:
glBegin(GL_TRIANGLES_STRIP)
glVertex3fv(0.000，10.000，0.000)
glVertex3fv(0.000，10.000，-10.000)
glVertex3fv(0.000，0.000，0.000)
glVertex3fv(0.000，0.000，-10.000)
glEnd()
wglSwapBuffers()
In the middle of this a series of calling, call the beginning of glBegin (GL_TRIANGLES_STRIP) expression triangular piece, represent its end and call glEnd ().Function glVertex3fv can be by three coordinate x, y and z definition vertex of a triangle.
When whole elements of front are changed into API figure 12 by graphical application 11 through calling above-mentioned function, graphical application 11 just causes by means of the suitable function of API figure 12, and what the above-mentioned element that changes such as " glFlush " function of pointing out in the above example or " wglSwapBuffers " function showed finishes.These functions impel to be finished whole two graphics commands that receive previously and changes map of current at graphics card 13 into as the bit image in the refresh memory, and this figure that receives previously that just is through with receives instruction demonstration on graphic alphanumeric display 14 as a result.
Have at graphics card 13 under the situation of two frame memories, instruction " wglSwapBuffers " also causes the transformation of 13 two frame memories of graphics card.
Under the situation of described demonstration example, the effect that receives instruction " wglSwapBuffers " is exactly to cause to demonstrate effectively on graphic alphanumeric display 14 by graphical application 11 to be converted to graphics command in the graphics card 13 by graphical interfaces.In the case, its effect is exactly to have finished the demonstration of the geometry entity of being made up of two triangle T 1 and T2 10 on this display 14.
Referring now to Fig. 2 and Fig. 3, narration uses method of the present invention to export geometric model.
When using method installation diagram graphic data written-out program of the present invention, the former DLL " opengl32.dll " that exists in the Widows system directory 12 is renamed to such as " opengl32bis.dll ", and it is implemented the inventive method and with original, and promptly the DLL15 that names of the mode that " opengl32.dll " is identical replaces.Have in the OpenGL standard and former DLL12 identical functions according to this DLL15 of the present invention, promptly for same title and same parameter, it gives the interface function identical with former DLL OpenGL12.
When the operator 2 who does not demonstrate wishes to export the data of the geometric model 10 of being set up and/or being handled by graphical application 11, enforcement the inventive method and aforesaid DLL have been used in advance.Want this moment display graphics to use 11 geometric models 10 of wishing.Use a computer system 1 and do not use the mode of the inventive method identical with described in front, when graphical application wishes to show a geometric model on display, used to be arranged in the DLL15 that the Windows system directory is named as " opengl32.dll ", promptly according to the OpenGL standard call function and the original program that in this DLL15, comprise.
Consider this, when the program of installing according to the output of the present invention data relevant with geometry entity, with using DLL15 of the present invention to replace DLL12, obviously graphical application was called the function that exists among the DLL15 that uses the inventive method and original program replace the function and the original program that exist in former DLL12 this moment.
In another embodiment, can the opengl32.dll of called after DLL15 only be installed so that be used for using specific Geometric Modeling or processing by DLL15 only is installed in specific application 11 catalogues.In fact, seek when being employed 11 specified DLL15 when Windows operating system, it at first seeks this DLL15 in using the 11 same catalogues that exist.If do not find, Windows operating system is just being sought this DLL15 subsequently in the predetermined catalogue of the system 1 of the system directory that Windows operating system is installed.
Therefore, when using method of the present invention and handling aforesaid example again, DLL15 of the present invention replaces original DLL OpenGL12, calls the graph function that is used for the latter.In the current Implementation Modes of the present invention, this moment, DLL15 of the present invention changed the function that calls reception into original DLL12, and promptly it calls the function that has with acceptance in deriving from the calling of graphical application 11 and has the respective function of the DLL12 of identical parameters.
As a result, DLL15 of the present invention has received following function calls:
glBegin(GL_TRIANGLES_STRIP)
glVertex3fv(0.000，10.000，0.000)
glVertex3fv(0.000，10.000，-10.000)
glVertex3fv(0.000，0.000，0.000)
glVertex3fv(0.000，0.000，-10.000)
glEnd()
wglSwapBuffers()
In order to export the data relevant with geometry entity, in its storer 16 and manage, non-exclusively show such as point " point " table and leg-of-mutton " triangle " by these tables with a certain amount of data table stores relevant with geometry entity for the program that comprises in according to DLL15 of the present invention.When beginning, these two tables are empty, and promptly the number of elements of the NTriangle of the N Point number of elements of some table and triangle table all is 0.
In the program of step 30 beginning DLL15, the N Point number and the leg-of-mutton N Triangle number of point all are initialized as 0 here, wait for the graphics command that receives from graphical application 11 then.When receiving instruction glBegin (GL_TRIANGLES_STRIP), method of the present invention just arrives step 31, and whether the parameter value that detects instruction GL_BEGIN here is the predetermined value of expression by the graphics command string GL_TRIANGLES_STRIP of its summit definition triangular piece.If the answer is in the negative, this method just turns to step 30, if parameter value is GL_TRIANGLES_STRIP in other words, this method just turns to step 32, waits for a graphics command at this.
When receiving a graphics command, method of the present invention just detects in step 33 whether the instruction that receives is instruction glVertex3fv, under the situation of present embodiment, answer is yes, call glVertex3fv (0.000 when having received, 10.000,0.000) time, method of the present invention just arrives step 34.In step 34, when having received the unit point of N Point, promptly N Point becomes at 1 o'clock by its initial value 0, just with the program increment among the DLL15.The point that will receive this moment is stored in the table, promptly in step 34, be under 0.000,10.000 and 0.000 the situation at numerical value, first, second of the instruction glVertex3fv that always will receive respectively and the 3rd parameter are stored on the position of coordinate x, the y of a table the first and z.Method of the present invention then just arrives step 35.
In step 35, whether method of the present invention detects the N Point of the point that receives less than 3.If answer is yes, method of the present invention will turn to step 32, otherwise method of the present invention just arrives step 36.
When the answer is in the negative when in step 33, this means to have at least three points to be transmitted by the instruction glVertex3fv of front.According to the OpenGL standard for the GL_TRIANGLES_STRIP triangular piece, this shows has determined one by back three triangular pieces that point is formed that receive.
Therefore subsequently in step 36, use the program DLL15 of the inventive method to increase the leg-of-mutton number that receives by a unit, promptly increase the leg-of-mutton N Triangle number that receives by a unit.This moment is the number n that constitutes the leg-of-mutton point that so receives
1, n
2And n
3Promptly according to back three points of the reception of OpenGL standard, be stored on the relevant position of triangle table, promptly number N Triangle-2, the N Triangle-1 of back three points that receive and the n of the N Triangle number position that N Triangle is stored in triangle table
1, n
2And n
3On the position.
At this moment, the algorithm branches at step 32 among the DLL15 is in order that wait for another possible point of the triangular piece that is transmitted by graphical application 11 here.
Method of the present invention is carried out step 32 repeatedly to step 36, till the answer is in the negative in step 32.
In the middle of described embodiment, after through 4 " glVertex3fv " instruction 4 points having been arranged, DLL15 no longer receives other " glVertex3fv " instruction, receives instruction " glEnd " but replace.In step 33, the answer is in the negative then, and this moment, DLL15 just arrived step 37.
In the middle of the OpenGL standard, under the situation of GL_TRIANGLES_STRIP triangular piece, instruction " glEnd " means that the graphics command by instruction " glBegin " beginning of front finishes.
In step 37, whether DLL15 to call be call function " glEnd " if detecting back of receiving.If the answer is in the negative, the program that comprises in DLL15 just turns to step 32.When the answer that detects in step 37 when being sure, the program among the DLL15 just arrives step 38.In the middle of described embodiment, when sending instruction " glEnd " after 4 " glVetrex3fv " instruction, graphical application 11 comes to this.
In step 38, the program that comprises in DLL15 of the present invention is waited for the instruction from graphical application 11, when receiving such instruction, just arrives step 39 then.
In step 39, the DLL15 program detects whether the graphics command that receives is OpenGL instruction " wglSwapBuffers " or " glFlush ".If the answer is in the negative, if the instruction that promptly receives neither " wglSwapBuffers " also non-" glFlush ", this moment, the DLL program according to the inventive method just was through with.If answer is yes in step 39, this moment, the DLL15 program just arrived step 40.
In the middle of described embodiment, after sending instruction " glEnd ", graphical application is sent instruction " wglSwapBuffers " to program DLL15 11 this moments, but also can use instruction " glFlush ".
As the front in the system of using a computer 1 and pointed need not method of the present invention the time, these instructions impel the transformation of finishing graphics command and the so-called appropriate display on display 14 thereof, therefore these instructions are implied and are comprised that the instruction of shifting previously forms the meaning of harmonious integral body, need not wait for other graphics commands because it should be presented on the display 14.
Then, in Implementation Modes of the present invention, it is harmonious whole and be used at this moment it is outputed to storage unit 18 to use these to instruct to determine which instruction that receives previously forms.
Then, when answer is yes when detecting in step 39, promptly when receiving instruction " wglSwapBuffers " or " glFlush ", the front is just formed harmonious integral body by the instruction that the program among the DLL15 receives, and this moment use the program among the DLL15 of the inventive method to arrive step 40, here, the module 17 of a Raider3D by name point and the triangle table that will be stored in the storer 16 outputs to storage unit 18.
In the method for the invention, the storer 16 of memory point and triangle table is a shared storage in the computing machine of implementing the inventive method therein, this means that it can be write by DLL15, is read by Raider3D module 17 simultaneously.
In first Implementation Modes of the present invention, point and triangle table output to unit 18 with the form of simple text, and its mid point and triangle are written in the file of the same name in the storage unit 18.
Now again referring to the ruuning situation of Fig. 4 narration according to the module Raider3D17 of first kind of Implementation Modes of the inventive method.
In this first kind of Implementation Modes, in step 41, module Raider3D17 generates in storage unit 18 and opens a some output file, and its title is " point " in described embodiment, it is the value initialization of the some i that writes in file " point " numerical value 0, just arrives step 42 then.
In step 42, whether module Raider3D17 detects the some i write in file " point " value is less than the numerical value of the some N Point that exists in shared storage.If answer is yes in step 42, module Raider3D17 just arrives step 43.In step 43, the value that module Raider3D17 will put i increases a unit, write the new value of an i then in file " point ", at three coordinate x, y and the z of the point that writes corresponding i with delegation, this point is duplicated by the input i that is stored in " point " table in the shared storage 16 then.This moment, module Raider3D17 arrived the delegation in the file " point ", turned to step 42 then.
If the answer is in the negative in step 42, module Raider3D17 just arrives step 44.In step 44, module Raider3D17 close file " point ", it just arrives step 45 then.In step 45, module Raider3D17 generates on storage unit and opens a triangle output file, and with its called after " triangle ", the value initialization of the triangle i that will write in file " triangle " is 0 then in described embodiment.Just arrive step 46 this moment.
In step 46, whether module raider3D17 detects the triangle i write in file " triangle " value is less than the numerical value of the triangle N Triangle that exists in shared storage.If answer is yes in step 46, module Raider3D17 just arrives step 47.In step 47, module Raider3D17 increases a unit with the value of triangle i, in file " triangle ", write current leg-of-mutton number i then, and duplicate the number n of leg-of-mutton three points of forming number i again by the value of the triangle i that is stored in the table " triangle " in the shared storage in the same delegation of file " triangle "
1, n
